 Lowering a toilet flange
Author: rdbertino (NJ)

I just removed an mortar bed and tiles from a bathroom and the flange is now 1 1/2 in" above the sub-floor. When I put new flooring down the flange will end up about 7/8" above the finished floor. I assume this is a problem. The flange appears to be copper and the 3" pipe it is connected to is cooper. The flange looks like it is connected to a about a 10"piece of pipe that is inserted down into the waste pipe. It appears to be one piece because I can feel a seam just below the flange on the outside wall of the pipe leading me to believe it is sitting on the waste pipe. Is the flange typically sweated on or can I pry it loose and cut the pipe lower and replace. Thanks for any thoughts on this matter.

you can heat the joint on the flange, pry it loose and lift it off.
it will be tricky to cut the pipe that is sticking up but it can be done. put the old flange back on, orient the bolt holes properly and solder it. solder can be added from the top.
if the cut you make on the copper tubing looks like a baloney cut, peen the copper over and solder it the way it is. it will be fine. use 50/50 lead bearing solder if you can.

I ended up cutting the sub-floor around the pipe so I could gain access to cut it properly. Heating the joint did eventually allow me to remove it so I was able to reuse the flange. Thanks for the advice.

Was the tile floor originally higher than the adjacent one, or do you now have a "step down" because of the thinner floor?
